the wavelength of the sound emitted by a dog is 0.009 m ; what is the frequency of the whistle ? ( use the formula : V= frequency x wavelength

• science -

V= 330m/s
Wavelength= .009m

Frequency= 330/.009 hz

• ultrasonic dog? -

The speed of sound in air varies with temperature. It is 331 m/s at 0 C and 343 m/s at 20 C. The whistle frequency would be 37,000 Hz.

I doubt if the dog emits the sound, as your question implies. It is the dog whistle that makes the sound.
